A driving circuit has a p-channel transistor and an n-channel transistor. An electronic component for interconnection is incorporated into an electronic device package in which a circuit element including a semiconductor chip is disposed and which has external electrodes connected to the circuit element via vertical interconnects and horizontal interconnects. A processing unit receives the detector signal from the current detecting unit, and processes the detector signal so as to output a power indicating signal that varies with a consumed power of the load. Any requisite user input or sample data that is required by these modules is automatically generated and provided to assist in the generation, display, and capture of the interfacesdialogues. A metering sleeve has on a bottom side an eccentric metering sleeve opening.
